Abstract

Systems and methods according to the present invention provide methods for wireless communications and devices associated therewith which vary the intermediate frequency based upon the particular channel and/or system with which a wireless station is communicating. Tailoring the selection of an intermediate frequency in this way, enables signal energy associated with images created by heterodyne processing to be more easily removed.
